Description

[Detailed description of the invention] This invention is a bag that can easily and safely cut the so-called sealing string such as tape or hemp string tied to the bag opening of small mailbags by using the action of a lever. This invention relates to a sealing cord cutter for tying the mouth.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

Reference numeral 1 denotes a handle, which is made up of two complements 1a and 1b that are put together and fixed with a fastener 2 such as a bolt.

Inside the complements 1a and 1b, grooves 3 for inserting a blade and a safety rod, which will be described later, are formed at the tip of the handle 1, respectively.

Reference numeral 4 denotes a blade, and a hook portion 5 is formed at the tip of the blade by bending approximately 90 degrees toward the blade edge 4a.

6 is a safety rod shorter than the blade 4, and the cutting edge 4 of the blade 4
It is provided opposite to a.

A plurality of mounting holes 7 are formed in each of the blade 4 and the safety rod 6.

The base of the handle 1 is inserted into the insertion groove 3 as shown in the figure, and a plurality of bosses 8 are provided protruding from the insertion groove 3.
They are removably inserted into and removed from the mounting holes 1, respectively.

In addition, a grindstone 9 for polishing the blade 4 is provided in the remaining space of the insertion groove 3.
is housed in a removable manner.

When using this configuration, as shown in FIG.
When the handle 1 is pushed in the direction of the arrow in the figure after inserting the hook 5, the cutting edge 4a cuts the string from the inside.

At this time, since the outside of the hook part 5 acts as a lever, the string can be easily cut without applying much force.

Further, since the safety rod 6 is located at a position opposite to the cutting edge 4a, there is no risk that the cutting edge 4a will come into direct contact with your hand or the like even if you make a mistake.

As described above, the present invention consists of a handle in which two complements are joined together and fixed with a fastener, a blade whose tip is curved toward the cutting edge to form a hook, and a nuclear force provided opposite to the cutting edge. The safety rod is provided with a safety rod, and the blade and the base of the safety rod are respectively inserted into and removed from the handle.

Since the present invention is constructed as described above, it is easy to cut the string tied to the opening of small mail bags, etc., and it is safe to work with.Moreover, the blade and safety rod are free from wear and tear. It has many advantages, such as the handle can be disassembled and removed for repair or replacement, and it is easy to assemble.
